BOTTLE.

SPECIFICATICNforming part of Letters Patent No. 718,017, dated January 6, 1903. .Application filed September 30,1901.k Serial No. 77,207. (No model.)

To all whom it may con/cern:

Be it known that. I, FRANK MARRYAT N oR- RIS, a subject ot' the King of Great Britain, residing at Hunterville, in the Colony of New Zealand, have invented new and useful Improvements in or Relating to Bottles; and I do hereby declare the following to be a full, clear, and exact description of the same.

This invention has been devised forthe purpose of providing means whereby the withdrawal of all or any ofthe contents of a bottle may be indicated and any refilling or addition to the contents without detection thereby prevented. The means employed for carrying out this object consist of a special form of double rack that is secured within the bottle and extends throughout the length ofthe body thereof. A pair of oats is provided. which are conn ectcd together by means of a connecting-piece that passes between the ratchets. This connecting-piece is provided on its upper part with angular projections that are adapted to engage with the projecting teeth of the ratchet-bar.

In order, however, that the invention may be `properly understood, reference will be made to the accompanying sheet of drawings, in which- Figure l is an elevation of a bottle with part broken away, so as to exhibit the double ratchet and float. Fig. 2 is a cross-sectional elevation of the same. Figs. 3 and 4 are respectively sectional elevation and underneath plan of the pair of floats with their connecting-piece.

o, is the bottle, to the inside of the body of which is affixed in any suitable manner the double ratchet-bar ZJ, that is formed with two rows of downwardly-projecting teeth c, facing one another. Passing through between the rows of teeth of the ratchet-bar b is a connecting-piece CZ, that is shaped as shown in section in Fig. 3, with angular projectionseupon its upper edge and with straight sides, which taper to a point on its lower edge.' To each end of this connecting-piece is attached a float f, that may be made of any material buoyant enough to float on the top of the liquid contents of the bottle. When the ratchet and the floats have been secured within the bottle, the floats are held up at the top by tying them to the neck until the desired contents have been poured in, when the oats will be supported and kept up bythe liquid. As the level of the liquid in the bottle falls by parts ot its contents being withdrawn the floats will fall with it. p Should any fresh liquid be poured into the bottle, the iioats will only rise a short distance until one of the angular project-ions e of the connecting-piece CZ engages with one of the teeth c of the double ratchet, as shown in dotted lines, Fig. l. The ioats will thus be prevented from rising higher,no matter what addition is made to the contents ofthe bottle.

The center ol gravity of the floats f, with their connecting-piece d, is so placed that the projections e shall always point upward, and thus be able to slide past the teeth ot the ratchet b in a downward direction, but will engage with the teeth c should any attempt be made to draw up the tloats.

To prevent the lioatsfand connecting-piece d being caused to work up the ratchets by a sudden 'inversion of the bottle, one of the lioats has loosely pivotedto it a pendent rod g, to the bottom of which a cross-bar is rigidly xed. This pendent rod hangs normally downward free of the ratchet-bars b; but should the bottle be inverted or partially inverted the rod will fall inward into the space between the two ratchet-bars, so thatits crossbar 7L will engage with the teeth of such ratchet-bars, and thus prevent the floats from moving up the ratchets. If desired, also the inside face of the cross-bar h may be serrated and the adjacent faces of the ratchet-bars b also serrated, so that should the cross-bar fail to enter between the two ratchet-bars when the bottle is inverted the serrations will cause the bar to grip upon the surface of the ratchetbars, and thus hold the floats from moving.

What I claim as my invention, and desire to secure by Letters Patent, is-

l. vIn bottles, a double ratchet-bar secured vertically within the body of the bottle and formed with two rows of downwardly-projecting teeth facing one another, in combination with a pair of floats one on each side of the bars and connected together by means of a connecting-piece passing between the rows of teeth on the ratchet-bars, such connecting- IOO combination with a loosely-pivoted pendent rod attached to one of the oats and provided with a cross-piece upon the bottom end thereof adapted to enter the space between the ratchet-teeth and engage therewith when the bottle is inverted as herein specified.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

FRANK MARRYAT NORRIS.
